So how does Zerona work? The Zerona laser has five laser-emitting diodes that can be manipulated to target a specific area of the body. The light emitted from each diode head forms a linear pattern when it comes in contact with any surface, and each beam rotates in a clockwise pattern to evenly cover the target area. When applied to a patient's skin the laser penetrates to an average depth of about 3.5 cm, which corresponds almost exactly with the location
of subcutaneous fat cells in the human body.

It is important to note that the Zerona laser differs from other lasers in that it does not burn or produce pain for the subject. This technology could be referred to as a "cold" or "low-level" laser, and is similar to the technology behind hand-held
devices used in sports medicine for the past decade.

What happens once the laser has penetrated the skin?
It turns out that the light emitted by the Zerona laser device oscillates at a frequency that temporarily disrupts the membranes of adipose cells, which are the fat-bearing cells of the human body. As the membranes of these cells are disrupted, a transitory pore (or hole) is created, which allows the lipids and fatty debris stored in the cells to be released.

But where does this fatty material go?
Once liberated from the adipocytes (fat-bearing cells),
fatty debris empties into the interstitial space (the
open space between cells of a particular tissue).
From here, the fatty debris is naturally absorbed by the body's
lymphatic system, and metabolized into energy and waste.
It is important to note that Zerona does not kill or
harm adipose cells: for 48 hours after each application,
affected cells become porous, empty their
fatty contents, and become temporarily deflated.
After this period, the cells resume their normal function and physiology, except that they are no longer harboring the same fatty debris they were storing before the treatment.
